The United States Supreme Court has rejected an emergency request from the Trump administration seeking to set aside thousands of California ballots linked to people whose citizenship status was questioned by federal officials. The decision came just hours before the final day of voting in the 2026 midterm elections. The case involved approximately 20,000 people on California’s voter rolls whom the administration had identified as potentially noncitizens. The court declined to intervene immediately, dealing another setback to the administration’s efforts to influence election procedures before votes were counted.
The Justice Department had argued that the ballots should be separated until officials could verify whether the people who cast them were eligible to vote. The administration said the measure would protect election integrity while allowing valid votes to be counted later. California officials strongly opposed the request, arguing that the federal government’s list contained errors and that removing ballots could prevent eligible citizens from having their votes included. The dispute became part of a wider legal battle over the role of federal agencies in elections, which are primarily administered by state and local authorities under the US system.
The Supreme Court did not publish a detailed explanation for its decision, which is common when the justices deal with emergency applications. No justice publicly dissented from the rejection. The ruling followed several earlier court decisions that had also refused to support the administration’s request. Lower courts had rejected efforts to separate the challenged ballots, while other judges questioned the timing and legal basis of the federal government’s demands. The latest decision therefore marked another defeat for the administration in a series of disputes involving voting rules and election administration.
California Governor Gavin Newsom welcomed the outcome, describing it as a victory for democracy. State Attorney General Rob Bonta also said the administration had repeatedly failed in its attempts to change the handling of California’s election. Both officials argued that the federal government should not use emergency court orders to disrupt the voting process. The Justice Department, however, maintained that its request was limited and intended to ensure that only eligible voters participated. The disagreement reflects the broader political divide over how election security should be managed and how much authority federal officials should have over state voting systems.
The reliability of the federal list became a major issue during the legal proceedings. A Justice Department lawyer acknowledged that the data could contain errors when questioned by a judge. That admission raised concerns because the list was being used to identify people whose ballots could be affected. California officials said the records appeared to include eligible voters and argued that setting aside their ballots could cause serious harm. The case also highlighted the difficulty of confirming citizenship status through government databases, which may contain outdated or incomplete information.
The dispute was not limited to the Supreme Court. A federal judge in Washington also ruled against the administration’s last-minute demands of California election officials, finding that the requests likely violated constitutional limits on federal authority over elections. Another judge expanded an existing order requiring the Justice Department to inform the court before pursuing certain investigations involving people identified through its noncitizen voter list. These decisions show how several courts have been asked to examine the administration’s approach to election enforcement during a highly sensitive voting period.
Voting in California had already been underway for weeks. The state sends mail ballots to its registered voters, and more than six million ballots had been returned by the time the Supreme Court considered the dispute. That made the timing of the federal request especially important, because election officials were already processing large numbers of votes. Any decision to separate ballots could have complicated the counting process and created uncertainty for voters whose eligibility had not been individually established.
The Supreme Court’s rejection does not end the wider debate over election security or the federal government’s authority to investigate possible voting violations. However, it means the administration will not receive the immediate court order it sought in this case. Election officials can continue processing ballots under the existing rules while the wider legal arguments remain unresolved. The decision also reinforces the importance of reliable evidence and established legal procedures when government action could affect the voting rights of thousands of people.
